Answer:

Product of 6 and a number would be 6x\\.

Nine more than a number? x/2 +9

Combine a number and 7? Either 7x or x + 7.

Step-by-step explanation:

Question 1 is relatively simple. 6 is a constant, so it can be inserted into any equation and maintain the same value. "A number" could represent anything, so we'll represent it with a variable. This gives you 6x (also 6*x)

Question 2 is the same as the first with 1 more step added to it. A number, as previously stated, is represented by the variable x. You divide this by the constant value of 2 to give you \frac{x}{2}. Nine more would add +9 to the expression. Your final answer would be \frac{x}{2} + 9.

Question 3. Combine is a bit vague, but it could be either addition or multiplication. This could give you either 7x or 7+x.

Hope it was helpful.

I’m confused please help

So x equals 30 because u did 180-150 and y is also 30 since you found x you then add 90 plus 30 and it will give u 120 then 180 minus 120 will be 60 then 90 - 60 because u are trying to find y, and u will get 30.

You put 15 over 65 is equal to 50 over x, then you multiply diagonally so 15x = 3250 then you divide both sides by 15 to get 216.67 which means 50 pencils equals 2.17 dollars

HELP ME PLEASEEE DJSUS JDIDJSJDHOSSJEJDKDHKS

Answer:

(8, 20)

Step-by-step explanation:

Let's input each values of the ordered pair given as options to see which one satisfy the equation y = 16 + 0.5x

==>Option 1: (0, 18)

18 = 16 + 0.5(0)

18 = 16 + 0

18 ≠ 0

Option 1 is incorrect.

==>Option 2: (5, 19.5)

19.5 = 16 + 0.5(5)

19.5 = 16 + 2.5

19.5 ≠ 18.5

Incorrect.

==>Option 3: (8, 20)

20 = 16 + 0.5(8)

20 = 16 + 4

20 = 20

CORRECT

==>Option 4: (10, 21.5)

21.5 = 16 + 0.5(10)

21.5 = 16 + 5

21.5 ≠ 21

Incorrect.

The answer is (8, 20)
